Put in a nutshell, a fraction is written in terms of two parts separated by a line in between: the number above the line is called the numerator and the number below the line is called the denominator. To solve this question, we can use the division method to get a decimal: simply divide the numerator 31 by the denominator 631 to get the decimal:
31 (numerator) ÷ 631 (denominator) = 0.049
That’s it! When you convert 31/631 to a decimal, 0.049 is your answer.
